S3 Folder Upload

s3-folder-upload is a Node.js utility designed for efficiently uploading local static file directories to Amazon S3 buckets. The package is currently stable at version `2.3.5`, with minor releases deployed on an as-needed basis to introduce new features, fix bugs, or update dependencies, rather than adhering to a strict release schedule. It utilizes the official AWS SDK internally, ensuring robust and reliable integration with S3 services. Key differentiators include its flexible credential management, allowing configuration via environment variables, direct parameters, or AWS IAM role credentials, and providing granular control over S3 object properties such as `ACL`, `CacheControl`, and `Expires` headers, which can be applied globally or per file. The module also supports optional CloudFront invalidation, streamlining cache updates after deployments. Additionally, it offers a command-line interface (CLI) for quick and programmatic deployments, making it well-suited for integration into CI/CD pipelines or for local development workflows managing static assets.
